CARL SGHLIOKEYSEN, OF BERLIN, GERMANY.

CHAIN-BUCKET ELEVATOR.

SPEGIFIGATlION forming part of Letters Patent No. 591,085, dated October 5, 1897. Application filed May 25, 1897. Serial No. 638,078. (N0 model.) Patented in Austria March 1i), 1897, No. 47,820.

To all whom it may concern:

Be it known that I, CARL SOHLICKEYSEN,& subject of the King of Prussia, German Emperor, residing at Berlin, Prussia, Germany, have invented certain new and useful Improvements in Chain-Bucket Elevators, (for which I have secured Letters Patent in Austria, dated March 10, 1897, N 0. 47,820,) of which the following is a specification.

This invention relates to a construction of chain-bucket elevator that can travel in a path of any desired form and whose buckets-have an, arrangement whereby they become automatically charged with the material to be transported and automatically discharge the same at the place of delivery. The arrangement may also be such that some of the buckets are charged with one kind of material and others charged with a different kind of material, these different materials being discharged either at the same or at a different locality. A single bucket may receive some of each material.

The buckets are peculiarly inclosed in frames and linked together and are caused by suitably-shaped guide-rails to travel along the desired path. By the construction adopted the use of the usual distance-bolts passing through the buckets, which are so. inconvenient for the conveyance of solid and semi fluid bodies, is done away with. The elevator is propelled by means of rollers or wheels which run on the guideways or track and support the weight and guide the buckets and also engage with the driving means and receive the impelling force. The bearings for the wheels are secured to the outer surfaces of the sides of the frames. The buckets are each provided with pins by which they eifect the opening of the device for receiving the material to be transported and with dischargeflaps that are opened atthe place of delivery.

The accompanying drawings form a part of this specification and represent what I consider the best means of carrying out the invention.

Figure 1 is a diagram in side elevation,

showing the parts in operation. Fig. 2 represents certain portions in side elevation. Fig. 3 is on a larger scale. It is a side elevation showing the action in passing the actuating and guiding wheels. Fig. 3 is a corresponding plan view of one of the buckets shown as contracted in breadth. Fig. 4 is a plan View on a somewhat smaller scale, showdumping the contents of the bucket. Fig. 7

is a side elevation on a larger scale, showing the provisions for delivering the material into the buckets. Fig. 7 is a transverse section of the parts disclosed in Fig. 7. Fig. 8 is a corresponding vertical section. Fig. 9 is a side elevation showing the parts in the position for holding up the flap or hinged bottom, so that the bucket will retain and carry the material. Fig. 10 is a corresponding front sectional elevation. Fig. 11 is a side elevation showing parts carried on each bucket in the positions assumed for allowing the flap to drop so as to unload or dump the contents of the bucket. Fig. 12 is a corresponding sectional plan view.

Similar letters of reference indicate corresponding parts in all the figures where they appear. a

The elevator-chain comprises rectangular frames A, the sides a of which, of fiat section, are stiffened by the transverse end bars I). These separate link-frames are connected to: gether by connecting-links c, pivoted to pins 0/, Fig. 3, on the frames which are spaced at equal distances apart-that is to say, the distance between the two pinson a link-frame is the same as the distance between the pins of two contiguous link-frames. The said pins are extended and carry beyond the connecting-links rollers c, which run on the guiderails cl and which also engage with the spaces between the teeth of the driving-wheels f. The buckets g are of a downward-tapering shape and fit into the link-frames A and are secured thereto by riveting or other suitable means. The guide-rails d are of angle-iron section, the rollers c of the buckets running upon the horizontal flange thereof. There may be a pair of continuous rails for the chainbuckets passing from the charging locality to the place of delivery and another pair for the buckets passing back to the charging locality, each formed with as many bends as required for guiding the chain-buckets in any desired direction. At the bends of the guide-rails the chain-buckets are prevented from leaving them by providing counter-rails h and guide-pulleys h, which retain the rollers in position.

The chain-buckets g are in some parts of their route guided by passing over suitablyplaced guide-rollers, the guide-rails being provided only in certain parts of their path, as where the material is charged into them and where the charges are emptied into chutes. At the charging-point the buckets travel on horizontal guide-rails and pass under one or more hoppers i 1', containing the material and which have sliding bottoms t, to which are pivoted rocking levers Z, so arranged at the sides of the hopper that as the buckets pass under them pins mm, projecting therefrom, come in contact with the levers Z and turn them, so as to cause the bottom 25 to slide open and allow the contents of the hopper to fall into the bucket. When the pins have passed the levers, balance-weights n, connected to the latter, cause them to turn back into their original position, thereby closing the sliding bottom t again.

When certain of the buckets are to be charged with one kind of material and others with a different material, I provide a corre sponding number of hoppers 11 2" over the buckets, and the levers of the hoppers and the pins m 'm of the corresponding set of buckets are arranged in different positions, so that the pins of the buckets that are to receive material No. 1 will only act upon the levers of the hoppers for material No. 1 and the same with regard to the hoppers and buckets for material No. 2. Fig. 7 shows such arrangement.

For automatically discharging the contents of the buckets into the chutes k at the place of delivery the bottoms o of the buckets g are hinged at one end and made to drop open.

Pivoted thereto are catches 12 which when the bottom is closed engage with a rail w on the side of the bucket.

Above the chutes 70 7c are arranged fixed pins s, that project in the path of the hook of the said catches 12 so that as the buckets arrive over the chutes the pins 8 force the catches off the rail and the bucket-bottom 4), thus losing its support, drops open and discharges the contents. As the bucket travels onward it passes over a roller w, carried in fixed bearings, which first presses on the bottom, so as to turn it upward on its pivot into the closed position, and then acts on a tail 0;

of the catch o so as to turn this back into the engaged position.

If there are two kinds of material, No. 1 and No. 2, in two sets of buckets to be delivered, respectively, each into a difierent chute, then the before-described opening devices are arranged in a similar manner to those of the charging devices, so that the pin over chute for No. 1 will only act on the catch of bucket containing material No. 1, and the same with regard to chute for No. 2.

The material may be received from two or more hoppers into one bucket by simply presenting the latter under the hoppers successively and equipping the bucket with the pins m m properly formed and arranged to open the bottom of each.

My invention may serve a great variety of uses, among which is the charging of blastfurnaces with the successive installments of fuel, ore, and flux, in addition to its obvious one of simply transporting all manner of loose material.

I claim as my invention- 1. In a chain-bucket elevator, a series of rectangular frames A, links 0 and equidistant pivots a, connecting the same together, a roller 0 on each pivot, in combination with a driving-wheel having equally-spaced teeth adapted to receive the rollers, and with elevator-buckets 9 carried in the said frames, all arranged to serve substantially as herein specified.

2. In a chain-bucket elevator making changes of inclination, a series of frames A,

links a and pivots a connecting the same together, which latter are set on the frames and spaced at equal distances apart, a roller 0 on each pivot, in combination with a drivingwheel adapted to receive the rollers, one or more other wheels adapted to keep the chain extended, and with means as the counter-rails h for preventing the chain from leaving the path in the reentering angles of the latter, all arranged for joint operation substantially as herein specified.

3. In a chain-bucket elevator, the combination with a hopper having a hinged bottom normally closed by a weight, of a series of rectangular bucket-carrying frames A, links 0 and equidistant pivots a connecting the frames together, a roller 0 on each pivot, stops on the frames for operating the hopperbottom, and a driving-wheel having equallyspaced teeth for receiving the rollers, all arranged to serve substantially as specified.

l. In a chain-bucket elevator, in combination with the buckets g linked together, and impelling means f, the guide-rails d and means as the hopperz' and its operating mechanism for charging such buckets, and with the bottom flap '0 hinged to each bucket as a means of closing the base, and with a hook or catch 0 engaging with the rail 10 carried with the bucket to hold the flap in the closed position,
